FIG. 1C is a view illustrating a hardware structure for a processor and a display control modice of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 1C, the processor (for example, the processor 120) may include a first processor 121 (for example, application processor (AP)) and a second processor 122. The display control modice (for example, the display control module 170) may include a first display control modice 171 for controlling a first display 151 and a second display control modice 172 for controlling a second display 152. The first display control modice 171 and the second display control modice 172 may be included as parts of the logic performed by the first processor 121 and the second processor 122, respectively. The first display control modice 171 may be connected to the second display control modice 172 of the second processor 122 through an internal interface circuit 125 of the first processor 121.

According to various embodiments of the present disclosure, the first display control modice 171 may control information display through the first display 151 based on (or in response to) at least one of events occurring from the electronic device 101, for example, the relative position between the first display 151 and the second display 152, an opened/closed state of a cover for the body of the electronic device 101, information to be displayed on the first display 151, a function or application to be executed through the first display 151, information to be displayed on the second display 152, a function or application to be executed through the second display 152, or a user input.

According to various embodiments of the present disclosure, like the first display control modice 171, the second display control modice 172 may control information display through at least a portion (for example, the transparent display area 153) of the second display 152 based on (or in response to) various events occurring from the electronic device 101. According to an embodiment, the second display control modice 172 may adjust the transparency of the transparent display area 153 in response to a specific event. According to an embodiment, the second display control module 172 may control a screen change of the transparent display area 153 in response to a specific event. The second display control modice 172 may control the transparent display area 153 so that at least a partial area of the transparent display area 153 displays an object (for example, image or text) in an opaque state and the remaining partial area has a transparent state. According to an embodiment, the second display control module 172 may generate an image obtained by capturing a screen outputted to the transparent display area 153 in response to a specific event. The second display control modice 172 may be implemented in a chip form (for example, the second processor 122) separated from the first display control modice 171 and may then be disposed at one of the body or cover of the electronic device 101.

According to an embodiment, the second display control modice 172 may include a 3D modice 183, a depth modice 186, an augmented reality processing module 189, and/or a visibility processing modice 192. According to an embodiment, when at least a portion of an image displayed on the first display 151 is seen through the transparent display area 153, in order to provide the visual effect that a corresponding image is seen in 3D, the 3D modice 183 may apply image processing (for example, shift) for 3D effect to the corresponding image to display it in the transparent display area 153. The 3D modice 183 may shift a screen outputted to the first display 151 to display it in the transparent display area 153. The 3D modice 183 may adjust the resolution of a screen outputted to the first display 151 or the thickness or brightness of a border to display the screen in the transparent display area 153. The image processing for 3D effect applied by the 3D modice 183 may include equalization, sharpening, noise reduction, histogram conversion (image quality improvement), face recognition, high frequency cut-off filtering (blurring), high frequency enhancement filtering (sharpening), angle conversion, size conversion, saturation conversion, brightness conversion, or template matching in addition to image shift. Herein, the template matching function may be a function for processing a specific object in an image to be highlighted when an image outputted through the first display 151 and an image outputted through the transparent display area 153 overlap partially with each other.

According to an embodiment, when at least a portion of an image displayed on the first display 151 is seen through the transparent display area 153, in order to provide the visual effect that a corresponding image is seen in 3D, the depth modice 186 may apply image processing to a corresponding image to generate images to be displayed on a top surface 154 and a bottom surface 155 of the transparent display area 153 so as to express the depth of the corresponding image. The depth modice 186 may adjust the size, shape, color, brightness, contrast, or border processing of a first image to be displayed through the first display 151 according to the display characteristic of the first display 151 so as to generate a second image that gives depth to the first image. According to an embodiment, the second image may be an image obtained by reducing the first image at a certain ratio. The depth modice 186 performs a control on the second image obtained by applying image processing to the first image to be outputted through the transparent display area 153, so that the second image is expressed to be seen in 3D to a user by using the first image displayed on the first display 151.

According to an embodiment, when the transparent display area 153 is configured with a multilayer, the depth modice 186 may generate a second image and a third image, which are obtained by reducing the first image at different ratios. For example, the transparent display area 153 of a multilayer structure may include at least a first transparent display layer and a second transparent display layer. The first image may be outputted from the first display 151, and then may pass through the transparent display area 153 and be seen. Simultaneously, the second image may be outputted through the first transparent display layer and the third image may be outputted through the second transparent display layer. The second image and the third image together with the first image, as 3D images, may be visually recognized by a user.

According to an embodiment, in order for the perspective recognition of the first image, the depth modice 186 may reduce the brightness of a screen outputted to the first display 151, blur the border of the first image, or soften the color. Alternatively, the depth modice 186 may deepen the color of the second image or process the border more clearly.

According to an embodiment, the image processing for 3D effect applied by the depth modice 186 may include shift, equalization, sharpening, noise reduction, histogram conversion (image quality improvement), face recognition, high frequency cut-off filtering (blurring), high frequency enhancement filtering (sharpening), angle conversion, size conversion, saturation conversion, brightness conversion, or template matching.

According to an embodiment, when it is determined that a user sees an external object or place through the transparent display area 153, the augmented reality processing modice 189 may display additional information 156 relating to an object or place within a user's view in the transparent display area 153. The augmented reality processing modice 189 may obtain additional information relating to an object or place within a user's view based on context information or user's view or face recognition information obtained using a sensor (for example, a rear camera sensor) functionally connected to an electronic device.

According to an embodiment, the augmented reality processing module 189 transmits a preview image captured using a rear camera sensor to an external server to obtain prediction information relating to an object or place within a user's view or additional information to be displayed in the transparent display area 153, from the external server. The additional information may include information on the position and height of a building, and a store or a restaurant in a building within a user's view. According to an embodiment, in order to reduce internal data processing of the augmented reality processing modice 189, the augmented reality processing module 189 may receive information to be displayed in the transparent display area 153 from an external server and may then display the received information as it is in the transparent display area 153 without additional processing. Through such real-time processing, the augmented reality processing modice 189 may reduce time delay or information distortion, each occurring during augmented reality processing.

According to an embodiment, the visibility processing modice 192 may perform image processing for the visibility improvement of information displayed through the transparent display area 153 and/or information passing through the transparent display area 153 to be seen.

The visibility of the same information outputted through the first display 151 and the transparent display area 153 may vary. In the transparent display area 153, due to the light transmission, the sharpness of information displayed may be lower compared to an opaque display area. According to an embodiment, although information of the same color is inputted through the first display 151 and the transparent display area 153, the color displayed through the transparent display area 153 may be lighter than the color displayed through the first display 151. In relation to this, the visibility processing modice 192 may perform image processing of various methods on information to be displayed through the transparent display area 153 based on the transparency characteristic of the transparent display area 153.

Additionally, according to whether information displayed on the first display 151 passes through the transparent display area 153, the visibility of information displayed on the first display 151 may vary. When the information displayed on the first display 151 passes through the transparent display area 253 to be seen, relatively lower sharpness may be provided compared to when the information does not pass through the transparent display area 153 and is delivered directly. According to an embodiment, in the case that a specific color is displayed on the first display 151, when the displayed specific color passes through the transparent display area 153 to be seen, a user may recognize a color lighter than the specific color. In relation to this, the visibility processing modice 192 may perform image processing of various methods on information to be displayed through the first display 151 based on the transparency characteristic of the transparent display area 153.

According to an embodiment, the visibility processing modice 192 may clearly process the border area of an object, such as an image or text, in a screen to be displayed through the first display 151 and/or the transparent display area 153. The visibility processing modice 192 may apply sharpness effect to the border area of an object. According to an embodiment, the visibility processing modice 192 may process darker the color or color sense of a screen to be displayed through the first display 151 and/or the transparent display area 153. According to another embodiment, the visibility processing modice 192 may process relatively darker color or color sense of a screen to be displayed on the first display 151 compared to a screen displayed through the transparent display area 153. According to another embodiment, the alternative is possible.

According to an embodiment, the visibility processing modice 192 may generate second information (for example, a second screen) to be displayed in the transparent display area 153 by applying a specified transparency adjustment value to first information (for example, a first screen) to be displayed on the first display 151. According to an embodiment, the visibility processing modice 192 may generate second information (for example, a second screen) to be displayed in the transparent display area 153 by applying a specified contrast adjustment value to first information (for example, a first screen) to be displayed on the first display 151. The contrast adjustment value may be a value (for example, statistical or experimental value) set to have the visibility of more than a certain criterion while the first screen passes through the transparent display area 153 to be seen.

According to an embodiment, when the transparent display area 153 has a multilayer structure including at least a first transparent display panel and a second transparent display panel, the visibility processing modice 192 may specify at least one of the first transparent display panel and the second transparent display panel as a panel outputting second information. Alternatively, the visibility processing modice 192 may output the second information to the first transparent display panel and the second transparent display panel at the same time.

According to an embodiment, the visibility processing modice 192 may determine the output direction of the second information in the transparent display area 153. The visibility processing modice 192 may determine the output direction of the second information based on the relative position relationship of the first display 151 and the second display 152. When the first display 151 and the transparent display area 153 are disposed to overlap at least partially with each other, the visibility processing modice 192 may output the second information in a horizontal direction. Alternatively, when the first display 151 and the transparent display area 153 are disposed parallel to each other, the visibility processing modice 192 may output the second information in a reverse horizontal direction. Alternatively, the visibility processing modice 192 may dynamically adjust the output direction of the second information according to an angle between the first display 151 and the second display 152.

According to an embodiment, when the resolution of the first display 151 and the resolution of the transparent display area 153 are different from each other, the visibility processing modice 192 may adjust the size of the second information (for example, a second screen) outputted to the transparent display area 153 to match the size of the first information (for example, a first screen) outputted to the first display 151. Additionally, the visibility processing modice 192 may perform image processing on the first information and/or the second information in order to allow the color, shading, contrast, or saturation of the second information (for example, a second screen) outputted to the transparent display area 153 to be similar to the color, shading, contrast, or saturation of the second information (for example, a first screen) outputted to the first display 151.

According to an embodiment, the visibility processing modice 192 may change the second information being outputted to the transparent display area 153 in response to an event recognized by a motion sensor relating to the second display 152. For example, the visibility processing modice 192 may dynamically adjust at least one of the sharpness, luminosity, contrast, or color of the second information (for example, a second screen) being outputted to the transparent display area 153 in response to a bending or hinge operation of the second display 152. Alternatively, the visibility processing modice 192 may dynamically adjust the transparency for at least a partial area of the transparent display area 153 in response to a bending or hinge operation of the second display 152.

In the above embodiments, although it is disclosed that the second display control modice 172 includes all the 3D modice 183, the depth modice 186, the augmented reality processing modice 189, and the visibility processing modice 192, various embodiments are not limited thereto. For example, the second display control modice 172 may include at least one of the 3D modice 183, the depth modice 186, the augmented reality processing modice 189, and the visibility processing modice 192. Hereinafter, additional information on the electronic device 101 is provided through the drawings described later.

According to an embodiment, when the cover 340 is folded to allow the display 370 to be disposed outside, the electronic device 300 may be driven with relatively low power compared to methods of driving other displays. For example, when the cover 330 and the cover 340 are aligned at a specified angle or to have a specified first angle range (for example, the cover 330 and the cover 340 are aligned at 180° or with a range of 120° to 210°), the electronic device 300 may perform a control function on the display 320 and the display 310 to be driven with a first size power.

Additionally, when the cover 330 and the cover 340 are aligned to have a specified second angle range (for example, the cover 330 and the cover 340 are aligned with a range of 0° to 30°), the electronic device 300 may perform a control function to cut off the power supplied to the display 320 and the display 310. During this operation, the electronic device 300 may perform a control function on the display 370 to be driven with a specified second size power (for example, lower power than the first size power). According to an embodiment, the display 320 and the display 370 may be configured with one transparent display physically or may be provided in the double overlapping form of the transparent display 320 and the transport display 370. When the display 320 and the display 370 are configured with one transparent display, they are configured with one piece of hardware. In correspondence to a hinge angle of the cover 340, the direction of displaying information and the size of power supplied may be defined differently. According to an embodiment, when the transparent display 320 is disposed to allow the cover 340 to have a specified first angle range, it may display an object in a first display direction (for example, text or image arrangement from the left to right direction order).

Additionally, when the cover 340 is disposed to have a specified first angle range, the transparent display 320 may be driven with the first size power. According to an embodiment, when the transparent display 320 is disposed to allow the cover 340 to have a specified second angle range, it may display an object in a second display direction (for example, text or image arrangement from the right to left direction order) as shown in the display 370 of FIG. 3C. Herein, the transparent display 320 may be driven with a different second size power than the first size power. First information outputted to the transparent display 320 (for example, the front direction) when the cover 340 is disposed in the first angle range and second information outputted to the transparent display 320 (for example, the bottom direction of the display 320 or the front direction of the display 370 in the case of a double panel structure) when the cover 340 is disposed in the second angle range may be the same or different. As mentioned above, in correspondence to a hinge state of a transparent display (for example, at least one of the display 320 or the display 370), the electronic device 300 may process driving power of a transparent display differently (for example, low power or specified normal power).

According to an embodiment, when at least one display among displays formed a certain position (for example, the cover member 410, 420, or 430) is activated, the electronic device 401 may control the activation of at least one speaker(s) formed at a cover member having the activated display. According to various embodiments, the electronic device 401 may provide various sound effects (for example: surround, Dolby, or stereo) through the activation or directivity control of a speaker(s) according to the coupling form or relative position between the electronic device 401 and the cover members 410, 420, and 430. The electronic device 401 may control the activation or sound directivity of at least one of a speaker(s) formed at a certain position (for example, the cover member 410, 420, or 430) according to the position (for example, opening, closing, angle, or direction) of a certain cover member (for example, 410, 420, or 430). According to an embodiment, in relation to the electronic device 401, an angle formed by one surface (for example, the inner surface) of the cover member 410 and one surface (for example, the inner surface) of the cover member 430 may be in a certain range (for example, 90° to 180°). In such a case, the activation or sound directivity of at least one speaker(s) formed at the cover member 410 and the cover member 430 may be controlled. Through the same or similar method to the above-mentioned method, the electronic device 401 may provide various sound effects (for example: surround, Dolby, or stereo) through a speaker(s) formed at the cover member 430 and the cover member 430. According to an embodiment, the electronic device 401 may select a speaker activated or deactivated according to at least a partial opened/closed state of the cover member 410 or the cover member 420. When the cover member 410 covers one surface (for example, the front) of the electronic device 401, the electronic device 401 may control the deactivation or sound directivity of at least one speaker(s) formed at one surface (for example, the inner surface) of the cover member 410 covering one surface of the electronic device 401 and may control the activation or sound directivity of at least one speaker(s) formed at one surface (for example, the outer surface) of the cover member 410. Through the same or similar method to the above-mentioned method, the electronic device 401 may control the activation or sound directivity of at least one speaker formed at one surface (for example, the inner surface or the outer surface) of the cover member 420.

FIGS. 6A, 6B, and 6C are views of applying visual effect (for example, 3D effect) to information to be displayed through a plurality of displays in an electronic device according to various embodiments of the present disclosure. An electronic device (for example, the electronic device 101) may include a plurality of displays including at least a first display (for example, the first display 151) and a second display (for example, the second display 152). The second display 320, for example, may include a third display (for example, the transparent display area 153) and according to a relative position between the first display and the second display, at least part of information displayed on the first display may be formed to be seen through the transparent display area.

FIG. 6A is a view illustrating a 3D effect display of an electronic device based on additional information according to various embodiments of the present disclosure.

Referring to FIG. 6A, a display control modice (for example, the display control modice 170) of an electronic device may perform a control function on a plurality of displays to add visual effect to information to be displayed and display the information. The display control modice may generate additional information (for example, first image information 615 or second image information 620) for adding visual effect (for example, 3D effect 630) to information to be displayed (for example, 2D image 610). According to an embodiment, a display control modice may generate additional information based on at least of a property of information to be displayed (for example, display type or display depth) or a visual effect type (for example, embossing effects or engraving effects). According to an embodiment, when information to be displayed is an image, image processing may be applied to a process for generating additional information in a display control module. For example, a display control modice may extract a property, such as the shape or depth of image information, to be displayed and may then generate additional information based on the extracted property. According to an embodiment, a display control modice may determine a visual effect type based on at least one of information to be displayed, image analysis information reception form an external electronic device, and a user's input. For example, when information to be displayed is an icon, visual effect may be embossing effect.

According to various embodiments of the present disclosure, when it is recognized that information 610 (for example, a 2D image) to be displayed through a first display is transmitted through a transparent display area and displayed, a display control modice may generate additional information for adding visual effect (for example, 3D effect) to the information 610. According to an embodiment, when the information 610 to be displayed is determined as an icon image, in order to add visual effect to the information 610 to be displayed with embossing effect, a display control modice may generate first image information 615 to be displayed through a first display to be transmitted through a transparent display area and seen and second image information 620 to be displayed through a second display to be overlaid with the first image information 615 and seen.

According to an embodiment, the first image information 615 may be generated in the same manner as the information 610 to be displayed and the second image information 620 may be generated as an image to express visual effect of the information to be displayed. On the contrary to this, the second image information 620 may be generated in the same manner as information to be displayed and the first image information 615 may be generated as an image to express visual effect of information to be displayed. This is just one embodiment and the first image information 615 and the second image information 620 may be generated through various methods.

According to an embodiment, by applying at least one image processing technique among shift, equalization, sharpening, noise reduction, histogram conversion, face recognition, high frequency cut-off filtering, angle conversion, size conversion, saturation conversion, brightness conversion, or template matching to a process of generating at least one of the first image information 615 and the second image information, the first image information may be generated as another image information different from the information 610 to be displayed.

In an electronic device, a first display and a second display are disposed to overlap each other, so that a plurality of physical layers may be formed. For example, by implementing visual effect with a combination of visual representations of each of a plurality of physical layers, an electronic device may derive relatively excellent visual effect compared to when visual representation for the same or similar visual effect is implemented through software image processing on a display having a single physical layer.

FIG. 6B is a view illustrating a 3D effect display of an electronic device based on image copy according to various embodiments of the present disclosure.

Referring to FIG. 6B, a display control modice (for example, the display control modice 170) of an electronic device may copy the 2D image 640 to generate a plurality of copy images 641 and 642 in order to convert the 2D image to be displayed through the first display and/or the second display into a 3D image and display the 3D image. At this point, each of the plurality of copy images 641 and 642 may be the same image as the 2D image 640 or may be generated by applying image processing for 3D effect to the 2D image 640. According to an embodiment, a display control modice may perform 3D rendering on a 2D image to generate the copy images 641 and 642.

FIG. 6C is a view illustrating a 3D effect display of an electronic device based on image copy modification according to various embodiments of the present disclosure.

Referring to FIG. 6C, when information to be displayed through the first display and/or the second display is a complex image 650 including a plurality of layers, a display control modice (for example, the display control modice 170) of an electronic device may distinguish objects 651, 652, and 653 for each layer to perform image processing (for example, 3D rendering) on the objects 651, 652, and 653 for each layer in the same manner or differently. According to an embodiment, a display control modice may process the border for the first object 651 to be clear and adjusts the size of the first object 651 to a certain size or a size set according to a comparison with another object (for example, the second object 652 or the third object 653), so as to generate a first conversion object 661 corresponding to the first object 651. A display control modice may adjust the sharpness and size of the second object 652 based on the first conversion object 661 to generate a second conversion object 662 corresponding to the second object 652. A display control modice may adjust the sharpness and size of the third object 653 based on at least one of the first conversion object 661 and the second conversion object 662 to generate a third conversion object 663 corresponding to the third object 653. According to an embodiment, a display control modice may adjust a relative arrangement position between the conversion objects 661, 662, and 663.

According to various embodiments of the present disclosure, a display control modice may analyze a source image 610, 640, or 650, calculate a parameter to be applied to an expression of visual effect (for example, 3D or depth) according to an analysis result, and apply the calculated parameter to a source image or an object in a source image, so as to perform image processing.

FIG. 7 is a view of displaying one 3D image for a given image through a plurality of displays functionally connected to an electronic device according to various embodiments of the present disclosure. An electronic device (for example, the electronic device 101) may include a plurality of displays including at least a first display (for example, the first display 151) and a second display (for example, the second display 152). The second display 320, for example, may include a transparent display area (for example, the transparent display area 153) and according to a relative position between the first display and the second display, at least part of information displayed on the first display may be formed to be seen through the transparent display area.

Referring to FIG. 7, a display control modice (for example, the display control modice 170) of an electronic device may perform a control function on a plurality of displays to display first information (for example, at least one of a left-eye image 720 and a right-eye image 730) relating to information 710 (for example, a 2D image) to be displayed through the first display and display second information (for example, the other one of the left-eye image 720 and the right-eye image 730) relating to information to be displayed through the second display. Through this, since first information and second information are provided through a method of overlapping and displaying information (for example, a 3D red/blue method), a method of displaying information through each display using an additional filter (for example, a polarization filter) in each display (for example, a 3D polarizing method), or a method of displaying information by a time-sharing through each display (for example, a 3D shutter glass method), more a variety of information may be provided or more visual effects may be derived.

According to an embodiment, a display control modice may generate or obtain the left-eye image 720 and the right-eye image 730 of a 3D image to be displayed in order to effectively display the 3D image. The display control modice 170 may assign the left-eye image 720 to one of the first display and the second display and the right-eye image 730 to the other one. The display control modice may control the first display and the second display through various methods according to a 3D image implementation method (for example, a red/blue glasses method, a shutter glass method, or a polarization method).

According to an embodiment, when the left-eye image 720 is assigned to the first display, the right-eye image 730 is assigned to the second display, and a 3D image implementation method is a red/blue glasses method, the display control module may perform a control function to allow the first display to display the left-eye image 720 through a red filter based image processing process and allow the second display to display the right-eye image 730 through a blue filter based image processing process.

According to an embodiment, when a 3D image implementation method is a shutter glass method, a display control modice may perform a control function on the first display and the second display to alternately display a first image (for example, the left-eye image 720) assigned to the first display and a second image (for example, the right-eye image 730) assigned to the second display through a time-sharing manner. Through this, an electronic device may implement a 3D image and derive the effect that an image is displayed at a frame rate obtained by combining each frame rate displayable in the first display and the second display. Therefore, a 3D image may be displayed with more excellent performance (for example, flicker phenomenon reduction). For example, an electronic device may display an image at 60 frames per second (FPS) through the first display and may display an image at 60 FPS through the second display. When a 3D image is displayed alternately in a time-sharing method through the first display and the second display by applying this embodiment, an electronic device provides the left-eye image 720 and the right-eye image 730 at 60 FPS, so that the effect that an image is displayed at a total of 30 FPS may be derived.
